[image]Rock Slide in Ophir - NASA/JPL/Malin Space Science Systems
7 May 2004 The dark streaks, just left of center, on the steep slope in this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image were formed by a relatively recent rock slide. The streak closest to the center of the image resolves into a series of small depressions, indicating the path of a large, rolling boulder. The rock slide is inferred to have been recent (i.e., within the past several Mars years) because it is so much darker than its surroundings--there has not been sufficient time ...

[image]Northern Plains Buried Craters - NASA/JPL/Malin Space Science Systems
22 December 2003 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows three circular features on the martian northern plains near 70.7N, 311.7W. These circular features are the locations of meteor impact craters that have been buried beneath the plains. Much of the northern plains shares this story, in which thousands of old craters have been filled or partially filled and then thinly buried beneath textured plains...

[image]Olympica Fossae - NASA/JPL/Malin Space Science Systems
MGS MOC Release No. MOC2-500, 1 October 2003 This 500th Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) captioned release shows some of the complex flow and channel features of the Olympica Fossae region in northern Tharsis. The story of the Olympica Fossae is still emerging and continues to be puzzling. There is evidence in the Olympica Fossae channels that a fluid with the physical properties of water may have been involved in creating some of the erosional forms, but there are also flow ...

[image]Landslide in Aureum Chaos - NASA/JPL/Malin Space Science Systems
15 May 2004 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the results of a small landslide off of a hillslope in the Aureum Chaos region of Mars. Mass movement occurred from right (the slope) to left (the lobate feature pointed left). Small dark dots in the landslide area are large boulders. This feature is located near 2.6S, 24.5W. This picture covers an area approximately 3 km (1.9 mi) across and is illuminated by sunlight from the left/upper left.
